Interface LobSupport

All Known Implementing Classes:
DelegatingLobSupport
@SPI({USE,IMPLEMENT,SUPPLY}) public interface LobSupport

Defines the database and driver policy for LOB creation, binding, materialization, type classification, mutation ordering, and VALUE LOB DDL.

Implementations must be stable and thread-safe. Do not retain JDBC metadata or another call-scoped object passed to an operation.

      Whether LOB locators must be created using JDBC Connection factories.

    • supportsMaterializedLobAccess

      default boolean supportsMaterializedLobAccess()
      Whether the driver supports materialized byte and String LOB access.

      default boolean useMaterializedLobWhenCapacityExceeded()
      Whether over-capacity varying mappings become materialized LOB mappings.

    • forceLobAsLastValue

      default boolean forceLobAsLastValue()
      Whether LOB assignments must occur last in insert and update statements.

    • isLobType

      default boolean isLobType(int sqlTypeCode)
